I'd like to know what really happened in history before going back. If some of that sweet space tech gets released now would be fine. If time travel is available to me it must be commertial, the travle agent would have plenty of sugestions.
Beside that, I've already traveled back in time from the future. It happens in my dreams. I try to block this as much as I can as I don't like the feeling of catching up to the new present, it's every disorientating.
I've always thought that it would be neat to be be an obsever watching the earth from space at a time lapse sort of speed.
